均苯型聚酰亚胺模塑粉的制备与性能
Synthesis and Characterization of Polypyromelliticimide Polyimide Molding Powders
摘要
Abstract
To improve the processability of the polyimide molding powder, a novel molding powder with twisted structure was prepared with 1,3-bis[4-(3-aminophenoxy)benzoyl] benzene ( BABB) and pyromellitic dian-hydride ( PMDA). The component, morphological structure, melt viscosity, thermal stability of molding powder and the mechanical properties of molding products were studied. The results show that the glass-transition temperature and melt viscosity of molding powder reduce markedly, compared with the traditional polyimides, because of the introduction of the flexible structures in polymer main chain. The polyimide molding powder exhibited excellent melt viscosity stability and thermal stability. The molding products also possessed outstanding mechanical properties and lower water absorption.关键词
